Specification of Letters Patent. Patent d J 17 1922 Applidation filed August 5, 1920. Serial no. 401,296.

ful Improvements inWindows, of which the following is a specification.

This invention relates broadly to w ndows, and more particularly to a window sash and means for supporting same.

The primary object of the invention is to provide a window having simple and efficient means whereby the sash thereofus secured against chance. displacement without the use of the usual guide strips, whereby the sash is secured in ad'usted elevated position without the use 0 weights and pulleys, and whereby the movement of the sash to and from elevated position is facilitated and bindin of the sash upon the casing or frame is e ectually prevented.

A further'object is to provide, in a window of the character mentioned, a sash equipped with a plurality of yieldably mounted disks which serve as ant1-frictionrollers upon which said sash travels as it is raised and lowered and also whereby said sash is both guided in its vertical movements and normally held against outward movement.

A still further object is to provide a window of the character mentioned in which the sash may be readily removed from the.

Figure 2 isan enlarged section on line.

Figure 3 is an enlarged fragmentary section showing the sash-locking means in operative position; i

Figure 5 is aside elevation of the locking pin, detached. 1

Referring to said drawings, 1 indicates the sides of a window frame, and 2 and 3 the upper and lower sashes which arefitted to and vertically movable in said frame. Each sash has a face plate 4 countersunk in the opposite edges of the vertical sides 5 of the frame thereof at points adjacent to the upper and lower ends of said sides, and rigldly attached to the innerside of said face plate adjacent to the upper end thereof is the upper end portion of a resilient metal plate or spring 6 which normally depends fiat against the said inner side of said face plate, as shown in Figs. 1 and 3. Said spring 6 is bifurcated from; its lower end upward throughout a suitable part of its length and has the. ends of its separated prongs curved to form forwardly facing seats 7 which constitute bearings for the opposite ends of a transverse pin 8 which carries a plain wheel or disk 9 of suitable size.

.Said disk is disposed partially within a recess 10 provided therefor in the side 5 of the sash frame and projects outward from said recess through a slot 11 in the face plate 4..

Fitted ineach of the sides 1 of the window frame in position to receive the projecting edges of the disks 9 carried by the upper and lower sashes are two vertically disposed channel members 12 constituting runways in which the disks of said sashes travel when the latter are raised and lowered. As shown, the disks 9 fit more or less snugly in said runways 12 and said parts cooperate to secure the sash in its proper position in the window frame and to guide the sash in its vertical movements- Formed at suitabl spaced intervals in the bottoms of each 0 the companion runways mounted in the opposite sides 1' of the window frame are seats 13 for the reception of portions of the peripheral edges of the disks, said seats being preferably formed by cutting away small portions of said bottoms, as shown. The disks are preferably so proportioned in diameter to the depth of the runways that when the former are received in the seats 13, the supporting springs therefor rest flat against the face plates 4. Further, said springs are made sufiiciently stiff that they effectually resist the tendency to permit said disks to withdraw from said seats produced by the wei ht of the sash, thus requiring that manua force be exerted for lowering a sash from an elevated position in which the disks rest in seats. As is obvious, suflicient force must be applied initially, in either raising or lowering a sash, to overcome the resistance of the sprin s 6 in holding said disks to their seats an to cause said disks to mount the bottoms of the runways. Having mounted said bottoms, said disks constltute ieldably' held anti-friction rollers upon w ich the sash is carried freely, or without tendency to bind on the sides of the window frame. v

Means is preferably provided whereby one or more of the dlsks 9 may be locked in any of the seats 13 provided therefor in the runways. As herein exemplified, said locking means consists of a pin 14 directed transverse'l through and rotatable in the side 5 of t e sash frame behind and adjacent to the disk 9. Said pin}- has a recess 15 formed'in one side of the. body thereof. In the normal position of said pin the recess thereof faces the disk, as shown in Fig. 1, and permits the latter to freely move relative to said pin to an extent required. However when it is desired to secure said disk against withdrawal from the seat engaged thereby, said pin is rotated to present the plain, or unrecessed, side 16 thereof to the adjacent periphery of the disk, as shown in Figs. 2 and 3, in which position it positively obstructs inward movement of the disk. As is apparent, said locking pin is in effect a cam which is rotatable into. and out of locking engagement with} the disk. Obviousl when one -or more 'of the disks are locke in their seats as aforesaid, vertical movement of thewindow sash is e'flectually prevented.

It will be noted that the necessity for employing the usual sash guiding strips attached to the sides of the window frame is largely obviated by the provision of the guiding means hereinbefore described, although one or more such stripsmay be used if referred, asshown at 17 1n Fi 2.

0 provide for ready remova and replacement of a sash, as for cleaning p uroses, channels or grooves 18 are rovided in one side 1 of the frame at, suitab e points which are relatively spaced to corres end with the relative spacin {of the .dis 9. Said channels or grooves ead outwardhori-- zontslly from the bottoms of the runways,

gradually decreasing in depth, as shown by otted lines in Figs. 1 and 2, as the edge of said side 1 is approached, and constitute ways through which the disks, disposed in register therewith, may pass in swin ing the adjacent side 5 of the sash frame into and out of proper position within the .window frame.

While we have herein illustrated and described the preferred form of construction of the various parts of our invention, it will be obvious that various modifications and changes in the form of some of said parts may be resorted to without departure from the spirit of the invention. It will therefore be understood that we desire to avail ourselves of such variations and modifications as come within What is claimed is-- In a window, a Window frame having vertical runwa s in the sides thereof, a window sash fitted etween said sides of said frame and having suitably located recesses in the sides of the frame thereof, apertured face plates covering said recesses, a disk mounted for rotation rearward of each face plate and projecting outward through the aperture of said plate into the adjacent runway and adapted totravel in the latter, seats formed at intervals in the bottoms of said runways, resilient means exerting yielding pressure upon each disk whereby the latter is held in said runway under yieldin tension,'a locking pin located rearward 0 each disk, said pin having a camlike portion and bein adapted for rotation to enga e said portlon with the eriphery of said dlsk at a int diametrica ly opposite said runway or preventing the latter from being forced back against said resilient means, and horizontal channels in one of the sides of the window frame through which the adjacent disks may pass in introducing and removing the sash, said channels gradually diminishing in depth as they approach the face of said window frame.

In testimony whereof we afiix our signatures in presence of .two witnesses.
